K&M 44192 Universal holder

The quality is the same as to ordinary floor based stand. However if you are putting an expensive instrument on wall like that you want to be sure. Since it only has one screw (not provide) you can put a strong screw tight on wall. However i would not take the risk as it can only prevent falling, but it can also fall from the sides. Therefore I put nails on the sides as well to prevent it from flipping on sides and falling. Otherwise good stand!
